Instance Property

scale

The x-, y-, and z-axis scale factors of the transform relative to its parent coordinate space.

Declaration

var scale: vector_float3 { get set }

Discussion

Together with the translation, rotation, and shear properties, this property defines the local coordinate space for any object affected by the transform, relative to a parent coordinate space. Use the matrix property to work with the complete transform.

If the transform includes time-based information, reading this property returns the scale as of the earliest time sample (as reported by the minimumTime property). Writing to this property erases any time-sampled data for the scale factor. To work with time-sampled data from an animated transform, use the scale(atTime:) and setScale(_:forTime:) methods.

var rotation: vector_float3

var shear: vector_float3

The x-, y-, and z-axis shear factors of the transform relative to its parent coordinate space.

func setIdentity()

Sets all factors of the transform to those of the identity transformation.
